DRILL.

SPECIFICATION forming part of Letters Patent No. 678,845, dated July 16, 1901.

Application filed February 4, 1901. Serial No. 45,960. (No model.)

To all whom, it nung concern/.-

Be it known that I, ISAAC WANTLING, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Drills; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in drills and to that class known as coal or rock drills.

One object which I have in View is to provide a drill having a combined support carrying a feed-nut to be engaged by a drill-rod, said support provided in its main body portion with a longitudinal socket, by means of which the same may be used as a grip-drill, and to a transverse opening in the support arranged to have a bar or rod passed through the same, which also engages suitable perforations in the frame of the drill, the arrangement of the support being such that it can be adjusted to any desired angle for drilling and be retained in such position.

Another object which I have in view is to provide a combined support for a drill-rod which while it is applicable for a post-drill may be employed with equal advantage as a grip-drill. By the provision of the longitudinal socket in the support it may be readily and easily attached to a grip-bar.

Another object is to provide said support with means for attaching and detachin g power mechanism for engagement with suitable gearing carried on the drill-rod and through which the same may be actuated.

To these ends my invention consists in the novel features and in the construction and arrangement of parts hereinafter fully described, and definitely pointed out in the appended claims following the description, due reference being had to the accompanying drawings, forming a part of the specification.

In the drawings, Figure 1 is a rear elevation of my device when used as a post-drill. Fig. 2 is a side elevation ot' the same. Fig. 3 is an enlarged plan of certain parts. Fig. 4 is a perspective, enlarged, of the combined support. Fig. 5 is avertical longitudinal section through said support.

In the drawings, Figs. 1 and 2 showa postdrill consisting of the bifurcated frame, of two uprights 1 and 2, connected at their upper and lower ends, respectively, by cross bars or braces 3 and 4, bolted or otherwise suitably secured to said uprights 1 and 2. The cross bars or braces 3 and lare each provided with a vertical bearing centrally disposed therein, and in these bearings are fitted the spindles 5 and 6 with ends arranged for a positive engagement with the wall of the coal or rock being drilled. The uprights or frame parts 1 and 2 are each provided with perforations 7 in their body at equal distances apart throughout their lengths and arranged when the uprights are secured to the ends that they will be directly opposite to each other.

8 refers as a whole to a combined support or bracket arranged to be placed between the uprights and held at suitable points therein. The support has the depending body portion 9, the lower end v10 of which is flared somewhat and provided with a series of perforations 1l in diameter equal to the perforations 7 in the uprights, and 12 is a squared portion of said depending body portion 9, in which is a longitudinal socket 13, opening at both sides of the support, and 14 is a thumb-nut passing through the wall of the squared portion 12, as shown. The top of said support is spread somewhat, so as to give the same the appearance of a T, the outer ends of which are formed into rectangular boxes 15 on opposite sides with openings 16 through them for a purpose to be described. The upper central face of the support is provided with a semicircular groove 17, threaded throughout its length, which forms the lower half of a feed-nut 18, which is made complete by the provision of the section 19, hinged to the support at 2O on one side and detachably secured at its opposite side to the support at 21 and held in place by the .pin 22. The sections 19 and semicircular groove 17 of the support when combined as shown in the figures constitute the feed-nut 18.

In the body portion 9 I have provided a perforation or opening 23 in diameter equal to IOO the perforations the uprights and lower flared portion l( It is to be noted that the perforations 11 i: ne portion 10 are arranged in an arc whose i'sl iius is struck from the center of the perforation or opening 23.

The support 8 when it is desired to use the same in connection with a post-drill is placed in the frame at a desired height and retained in such position by passing a rod 24 through perforations in the uprights, which are coincident with the opening 23 in the support, and a looped extension 25 of said rod is passed through the next lowest perforations in the framein such a manner as to engage a desired perforation 11 in the lower body of the support. In this manner the support is locked firmly to the uprights and in such a manner as to be easily removed, and by providing the perforations 11, struck on a radius from the perforation 23, I can shift the support at suitable angles and lock it against movement, which will enable me to drill at all desired heights and at different angles. When the support is in its proper position between the uprights and locked against movement, the outer walls of the boxes 15 will lie adjacent to the inner faces of the uprights.

The provision of the rectangular boxes 15 is to provide suitable bearing for a detachable support -for gearing and means to actuate such gearing to impart movement to the drill-rod, and by the provision of two such boxings the drill may be used as a single power-drill or a double.

26 is a drill-rod having the forwardauger portion and the rear threaded portion with a suitable groove 27 extending the length of the threaded portion, and 28 is a pinion loosely carried on said drill-rod and provided with a spline fitting in said groove.

29 is a detachable frame-support arranged to be adjustably secured in the opening 16 of the boxing 15, and on its outer ends is provided the bearing 30.

31 is a spindle suitably journaled in said boxing 30 and is arranged to carry a bevelgear 32, intermeshing with the pinion 28 on the drill-rod.y The spindle is provided with an extended portion and a handhold for actuating said spindle. This manner of applying power to the drill enables me, by adjusting the support 29 in the boxing so as to bring the bearing thereof close to or removed therefrom and using suitable size gear for intei-meshing with the pinion 28, to-increase or decrease the speed of the drill when necessary without disturbing the drill parts or main supports, and if it is desired to double the power on said drill-rod it is only necessary to duplicate the power mechanism on the opposite side of the support 8, as has been shown and described for one side. In this class of drill it has been diiiicult heretofore to construct the parts in such a manner as to quickly and readily change from a post-drill to a grip-drill, as the operator has had to contend with a drill mounted in a frame on trunnions extending out from the sides of the boxing carrying the feed-nut and to secure the same in brackets attached to the uprights; but in the present invention I believe I have overcome all such diiiiculties by providing a feed-nut and support all in one piece, and have not only constructed a drill capable of being quickly and easily changed, but have made it possible to change to a grip-drill where it is not necessary when drilling a long cut to have to stop and change the angers, but accomplish with one auger what has been accomplished with three.

I do not wish to limit myself to the exact construction nor to the detailed arrangement of parts, as it is obvious that various changes may be made and details resorted to without affecting the principle of invention herein.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. In a drilling-machine, the combination of the supporting-frame of uprights having apertures facing each other, the boxing of two hinged sections, the lower section having extended bodies at opposite angles, one of said extensions having an aperture 23, and a series of apertures 11, lying in an arc struck from the aperture 23, and means of locking said boxing between the uprights, which said means is caused to engage the apertures in the uprights and the apertures-23 and 11 of the boxing, substantially as shown and described.

2. In a drilling-machine, the combination with nprights 1 and 2 connected top and bottom by suitable castings and each provided with sets of perforations, of the boxing of two hinged sections together forming a feed-nut, the lower section having an extended body 9, with a transverse aperture 23 and the boxing supported in said frame by means of a pin or similar device arranged to be passed through corresponding apertures in the uprights and the aperture 23, in a detachable manner, substantially as described.

3. The support S, having the depending portion 9, and liared or winged bottom lO, the depending portion 9, provided with aperture 23, and the winged portion with apertures 11,
